颈横动脉对臂丛神经影响的应用解剖

目的探索臂丛的周围血管——颈横动脉是否对臂丛神经造成卡压以及解决的方法。方法选用陈旧性成人尸体31具62侧,在胸廓出口部位进行颈横动脉的应用解剖学研究，重点是它与臂丛神经的关系。结果13侧未见颈横浅动脉，49侧中出现51条颈横浅动脉，其中11条与臂丛神经有紧密接触，占21.15%。16侧未见颈横深动脉，46侧有52条颈横深动脉（肩胛背动脉），其中31条与臂丛神经密切接触，9条在臂丛神经上留下明显压迹，占17.31%。结论颈横动脉，尤其是颈横深动脉（肩胛背动脉）可以形成对臂丛神经的卡压，是又一个可能导致胸廓出口综合征的原因之一。

Influence of transverse cervical artery on brachial plexus:application anatomy

Objective To investigate whether brachial pleuxs entrapment by transverse cervical vessels exited or not and provide its treatment option. Methods Application anatomy study of transverse cervical artery at thoracic outlet was done on 62 sides of 31 adult embalmed cadavers and its relationship with brachial plexus was noted.Results No transverse superfical cervical artery was found in 13 cases of cadaver anatomy. 51 transverse superficial cervical artery were found on 49 sides with 11 close contact with the brachial plexus (21.15 %); No transverse profound cervical artery was found in 16 cases. 52 transverse profound cervical artery (dorsal scapular artery) were found in 46 sides with 31 close contact with the brachial plexus, and with 9 having remaint brachial plexus impression (17.31%). Conclusions Transverse cervical artery,especially transverse profound cervical artery (dorsal scapular artery)can entrap the brachial plexus. It is another one of factors resulting in thoracic outlet syndrome.
